@Temple - hope you are feeling re-assured - just being diagnosed is enough to 'put us in a spin'. All the attention plus the ginormous machines, how they look, the noises they make - the whole production can be very nerve wracking. Its very ok to admit to being overwhelmed or scared and I agree that a counsellor and seeing your GP might help. When I was diagnosed (8yrs ago) I asked my oncologist for something mild to help me sleep and lessen my anxiety, she was happy to oblige. I've found it useful and supportive to talk with my Breast Care nurse rather than a friend or family member. Its ok to ask someone to go with you to any appointment or procedure, I find it such a relief to walk out of treatment to a friendly and familiar face.
